IMPROVEMENT IN MACHINES FOR MAKING MOULDINGS` TO ALL WHOM I'I MAYCONGERN:

Be it known that I, NICHOLAS JENKINS, of the city and county of NewYork, and State of New York, have invented certain new and usefulImprovements in Machines for Panelling and Variety Moulding; and I dohereby declare that the following is a full and exact descriptionthereof.

I will first describe what I consider the best means of carrying out myinvention, and will afterwards designate the points which I believe tobe new, reference being had to the two sheets of drawings, whichrepresentl the novel parts of my machine with so much of the other partsas is necessary to indicate their relations thereto.

Figure 1 is an end View of the machine.

Figure 2 isa front view of the main portion of the machine and across-section of the templet and of the wood which is being operated on.v

Figure 3 is a central vertical section through the lower end-of one ofthe cuttingiarbors.

Figure 4 is a horizontal section on the line S S in fig. 3, as seen frombelow.

Figure 5 is a central Vertical section showing another form of thecutter and its connections.

Figure 6 is a plan view seen from below.

Figure 7 is a top view ofone form of my templet.

i Figures 7 A and 7 B represent cross-sections of the parts detachedfrom each other.

Figure 8 is a top View of the wood lafter it has been panelled.

Figure 9 is a cross-section of the same; and Y Figure 10 is across-section showing the piece which is tted in the table to adapt themachine for variety moulding.

Similar letters of reference indicate like parts in all the figures.

A is the foundation or the main framework, and A1 is the xed portion ofthe head supported firmly thereon. Bl B are the arbors, mounted incarriages O1 C2 which are adapted to move vertically n dove-tailedchannels as is usual in this class of machinery. The ordinary loosepulley above, with the driving-pulley and belt, the latter capable ofbeing shifted from the loose pulley B3 on to the pulleys mounted on theupper extremity of the respective arbore, B1 and B2, are all of theordinary construction, and are operated in the ordinary manner. D isacross-traversing carriage adapted to slide horizontally in a head, w,which is adapted to move vertically in the head A1, as represented. E isa movable table on which the work is operated in either. directionhorizontally by the aid of the cranks, as represented. The operatorholds the two cranks, onein each hand, and by turning one or bothsimultaneously in one direction or the other, moves the carriage E inany direction desired, according as is required to produce the properpattern. This portion of the operation is identical with that of manyother approved forms of panelling and variety moulding machines. El E2are clamps operated by the thumbscrews e1 e, and adapted to press uponand firmly confine the templet and the wood which is' to be operatedupon. G is the main or exterior templet; G is a templct adapted to fitaccurately within the templet G. There may be still other templetsfitting within the templet G', if preferred. The inner and working edgesof these several templets may be alike in form and proportion, or may bevery diverse, as preferred. But the thickness of the several templets isequal, or about equal, and the exterior of one corresponds with suchaccuracy as to it immovably within the interior surface of the templetor portion of the templet which surrounds it.

In operating my machine the exterior templet Gr is applied first uponthe wood H, and is firmly clamped by the clamps El E2. After the cuttershave traversed quite around the interior of these templets, and produceda. corresponding panelling cut in the wood II, the cutters are liftedand the next succeeding templet G is dropped into place. The same ordifferent cutters are now applied and traverse around the interior ,edgeof the templet G. c c are notches formed in the sides of the carriagesO, and adapted to sustainthe latter and their connec" tions by a hookreceived therein. I, in figs. 1 and 2, is the main body of my hook; itis adapted to turn on the pivot z', and is acted on by the spring Jtending to force it into contact with the carriage C. K is a' movablehook-,piece mounted in the main body I; it is traversed up and down inthe latter/by means of 'the thumb-screw L. By turning this latter in onedirection or the other` the hook-piece K is raised and lowered with thegreatest accuracy, and adjusted as inely as may be required, while, bysimply pulling the entire body I and its connec tions away from thecarriage C, in opposition to the gentle' force of the spring J, I ableto' liberate the carriage C, and to raise and lower it immediately so asto shift the hook into the next notch above or below, or to raise orlower it to any great extent desired. I have represented only one of myimproved hooks. Both may be silch in practice. M is a hand-lever turningon the pivot m, and connected to the sliding head D and C so as to raiseand lower the latter with great facility. Nis a lever, turning on thepivot n, and actuated by the coiled springN so as to hold its cuttingedge in contact with the transverse sliding-head D.' There are twonotches in the latter which are adapted to receive this lever N, andhold the transverse-sliding head D stationary when one of the shafts orbevelling-arbors B is exactly in line with the loose pulley whichcarries a belt above. This part of the mechanism is analogous to that incommon use in this class of machines.

I will now describe the provision for raising and lowering the cuttingparts 'simultaneously and adjusting them at diii'erent heights. v

Wis a vertically-traversing carriage; it is guided on upright vways A2formed on the fixed head A1. This carriage W carries the -brackets whichsupport the loose pulley,.before described, .and also supports theseveral working parts which are driven by the power derived from thebelt. The dove-tailed horizontal grooves Aor ways provide for thelateral traverse of the carriage D. The lever N is pivoted upon thisvertically-traversing carriage IV. This mounting of so many oftheworking parts upon a single vertically-traversing carriage gives veryimportant advantages which will be readily recognized by those familiarwith this class of machinery. It carries the horizontal carriage D andall its several immediate connections, also the lever N, also the stoutupright arm A3, which supports-the loose pulley B3, several times abovereferred to, also the belt-shipper and the friction-spring and guideswhich hold it in the required positions. The means of adjusting thiscarriage -W in the required positions up and down on the slides A2 arepartly indicated in the drawings, and thereinainder. will be readilyunderstood. X is a hand-crank, which turns a shaft, 1:, which carries asmall spur-wheel, indicated in dotted lines in fig. f2. This wheelmeshes into a rack en the face of the upright A1, and by turning thehand; crank X the entire carriage W is 'moved up and down. In order tohold it in any required position, and yet allow it to be adjustedreadily and rapidily without the necessity for liberating any ordinarypawls, set-screws, or the like, I provide the springY which is connectedat each end to the carriage W, and presses its coils,near the centre ofits length, against the notched wheel represented on the shaft X. Thisserves as a'kind of springpawl by catching in the several recesses ornotches in this wheel. It holds with suihcient force therein to supportthe weight of the parts, but not with so great force as to prevent thecrank X from being readily turned in either direction when required. i yy i I will new describe the peculiarity of the cutter-head and itsconnections. O is a brace, bolted upon the under side of one of thecarriages Cl or C2. Both may be alike. I will describe simply that whichis attached to the carriage Gl. The lower end of the arbor B* isthreaded, as represented in iig. 3, and matches a female screw on theinterior of` the shell or hea-d P. The cutters, carefully worked to theproper form to produce the panelling desired, are bolted upon thesquared parts of this latter shell in the manner represented. Figs. 6and 'i' show an adaptation of the arbor B to receive the stem of thecutter internally. This construction may be used in connection with theone shown Vin fig. 3, and is, it will be perceived, so represented. Fig.(i shows the same construction as is shown in g. 3, but with the furtheradaptations now to be described. Q is a pinvo` cast steel adapted to titinto a corresponding socket bored in the lower end of the arbor, whichwe will continue te describe as B1. It is confined and released thereinby the pinching-screw represented, and is adapted at its lower extremityto remove the Vwood tovth'e desired pattern. V is a screwed thimb'le,having a projecting lip `or iange adapted to form a shoulder as it isscrewed up into a hole in the brace O, which is threaded to receive it.The lower extremity of this thimble V is slender, and encircles the pinQ without actually touching it so as to create any appreciable friction.This extension V1 is turned perfectly round, and is polished nicely, andforms a surface against which the several templets, above described, maybc successively traversed in panelling by the aid of my machine. It willbe perceived that this thimble V rises and sinks with the cutter and isalways in immediate proximity to the cutting portion. R, fig. l, is apin, which in its present position performs no function except that ofbeing held and holdingthe ring T against being lost. Its use is to tinto the hole represented in dotted lines in the table E, and in theunder table F, and in the main body A, so as to hold all these parte ina xed position when desired for variety mouldi'n My device for adaptingthe machine to produce variety mouldings is very simple and easilydescribed. T is. a; ring of metal, carefully turned and polished. It tsnicely in the corresponding circular recess, indicated in dotted linesin the table E. This recess is so related to the holes which receive thepin It that it is exactly in line with the loose pulley B3 when thetable E is locked in position. In applying my wood for variety mouldingI apply.y it upon the top ofthe templet, holding it by spurs thereon, asis common in some of the best machines of this class. On pressing thetemplet with the 'wood thereon against the ring T, and moving it aroundthe cutters, reduce thc wood to the corresponding form in the samemanner as with other varetymoulding machines, except that the work isperformed bythe same machine as performs the panelling above described,with this very slight modification. There may be two or Amore of A,theseguides T, if'desired.

Some of the advantages due to certain features of my invention may. beenumerated asfollows:

First, by reason of the fact that my adjustable hookY Iz K isconstructed' lwith* a' capacity for delicate adjustment'of the part K upand down and arraugedutojopera'tein connection withthe notches'in theslidingcarriage C,V as. represented, 'I am able to graduate the depthetowhich thecu-tters act with extreme nicety, while the carriage is securedandreleased with all the easeand rapiditypossiblevwith other andordinary hooks.

Second, by reason of thefact that the guide V is round, and is mountedconcentric to the arborof the cutte'r, am able to control the action ofthe cutter so as ytitftraverse it along the edge of a templet withoutsubjecting the guide or the tmplet toany friction due to the lrotarymotion.

Third, by reason of the fact that my .ring T is' adapted to be tted atpleasure in the recess in thebed E.

and to be so Aheld there exactly in line with the cutter above, I amable to manufacture variety monldings with the same machine as isemployed for panelling, and with very little trouble or expense in thechanging of the machine from one condition to the other.

Fourth, by reason of the fact that the templets G t over instead ofunder the wood H, and that the :machine is provided with meansrforfirmly holding both upon the table E, and for moving the latter in alldirections, as required, I am able to executctlarge Work with a-smallmachine7 and to guide the material vith great certainty and ease. Y

` Fifth, by reason of the fact that my templcts GG', Sec., are fittedaccurately one within the other, as represented, I am able to execute asuccession of operations upon these-me piece of wood H, by dropping inthe successive inside templets and changing the cutters, if' necessary,'by running the cross-head D across or otherwise without liberating andreadjusting the-wood o r the original external templet; I am, therefore`able to secure a mathematical exactness of position without any labor orcare.

Sixth, by reason of the fact that the single head w carries the entirecross-head D and the connected paris, so that it is capable of'beingraised and lowered with ease to any extent usually required Withoutrequiring any adjustment of other parte, I am able to operate ondilferent thicknesses of wood properly and with equal effect without amoments delay and withoutl deranging any of the varied capacities andnice adjustments of the machine. I
